I somewhat agree...but it almost pains me to leave it alone because as you know, I also love porting anything I can get my hands on! It is without a doubt the best stock intake manifold I've ever seen though.

You'd think with a ported TB you could at least hog out the inlet and see a few whp gain? Can that be done w/o removing it? Quick/dirty, that's what I'd do on a CT9A if I were to do it all over again with a ported TB.

Damn it stop giving me ideas. :P

The ported throttle body just removes the lip and smooths things out pre-plate, the diameter post-plate is left about the same. Let me go double-check my throttle body pictures to confirm that though...

No long-tube headers and definitely no cam Drivability needs to remain 100% stock-like with little to no additional noise in Tour mode (muffler baffles shut); these are my self-imposed requirements.

As of right now the C7 guys are just porting the stock intake manifold as there is nothing yet available in the aftermarket (or simply leaving it alone), but results have been mixed and I've seen nothing mega concrete yet in terms of gains. The C6 guys either port the stocker (totally different design), or get an aftermarket and have that ported (FAST, MSD, etc.).

I sent the stock intake manifold core in to Fasterproms in Florida for them to do their thing on it.

Porting is always tough to judge in pictures, but I'm very happy with the craftsmanship and finished product. The inlet and runners were all enlarged to gasket size, the vacuum/draft tube was removed, and all edges/lips were smoothed. This is what I would consider to be a "stage 1" level of porting, kind of like a Buschur intake manifold vs. a MAP Rev2 & 3. WeaponX (I have their ported throttle body) offers what I consider to be the stage 2 & 3 levels of porting, but for my plans the additional expense wasn't justified IMO.

I have a buddy coming to town from Arkansas next weekend to pick-up his Evo X build from Cobb so while he's here we're going to get some wrenching time in and install this manifold. Once I get the retune finalized, I plan to dyno again at Cobb since that's where I did my stock baseline at, then call my setup good for the year and just enjoy the hell out of the car!

Keepin it simple and clean, really diggin it man. If only I had the discipline (and $$$) to do the same!

Thank you..I feel you though, its a struggle! I actually bought, then canceled, a Procharger kit last month My goal is to keep things warranty, stock tune, and emissions compliant for my trips to the dealership. I also told myself I would not do anything to this car that in any way hurts reliability, drivability, comfort, etc. (something I've been guilty of on pretty much ever car I've previously modified). I want to be able to take cross-country roadtrips, then tear it up as soon as I get there

I figure it should be sitting somewhere around 450whp (Dynojet) with torque just a touch lower (440-445) for the Spring Cruise. This is on 93, I'll have to get a 91 safe tune made too for the middle states without the good stuff. Luckily my tank is big enough to do the entire cruise route on a single tank so regardless of what's available in southern MN/WI and Iowa, I'll be able to run 93 from Minneapolis.

I like that you're keeping it simple with the car. After going big all those years ago, I'm enjoying a smaller, better driving setup. I'm planning on getting another Esprit and the more I read about it, I'll just be doing basic mods instead of going crazy with it. It's fun to just enjoy the car.

I couldn't agree more. No major wrenching sessions, no drivability issues, etc. It's nice to just be able to drive the car whenever, and wherever, I please. I figure I should be able to knock the intake manifold out in about 2 hours Saturday morning, clean up, and be eating BBQ before noon.
